Title: Data-recording/reproducing apparatus and first seek-controlling method in the apparatus
Inventor: SHIBATA SATOSHI
IPC: G11B21/08
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent obstacles to a head or a disc by detecting quickly the runaway of a VCM generated when servo data cannot be obtained because of some reason at the time of a first seek, and preventing the head from colliding against a stopper. SOLUTION: A CPU 21 drives an SPM 13 thereby to start a first seek for removing a head 12 from a CSS zone and moving to a data zone. The CPU 21 instructs a VCM driver 17 to feed a current to a VCM 15 for removing the head 12 from the CSS zone. As a result, the VCM 15 is driven to move a carriage 14. The head 12 fitted to the carriage 14 is consequently moved in a radial direction of a disc 11 to the data zone, and becomes able to obtain data of a servo area. The CPU 21 checks whether or not the servo data are obtained. If the servo data cannot be obtained, a voltage at both ends of a coil of the VCM 15 is read, and compared with a reference voltage Vc to detect whether the head runs away out of control. When the head is judged to run away, the VCM is stopped and the first seek is cancelled.

Title: Manufacture of magnetic head
Inventor: KADONO MASARU
IPC: G11B5/127
Filed: 1990-09-10
Abstract: PURPOSE:To form a thick soft magnetic film on a non-magnetic base plate by using the specified non-magnetic base plate to be enlarged at a minimum heat treatment temperature for relaxing residual stress excepting for thermal stress generated when forming the soft magnetic film. CONSTITUTION:When forming the core of the magnetic head by laminating the soft magnetic films on the non-magnetic base plate, as the non-magnetic base plate, specified one is used to improve the magnetic characteristic of the soft magnetic film by enlarging the degree of thermal expansion at the minimum heat treatment temperature for relaxing the residual stress excepting for the thermal stress generated when forming the soft magnetic film in comparison with the degree of thermal expansion in the soft magnetic film. The thermal stress generates stress in the soft magnetic film after a heat treatment. Thus, by using the non-magnetic base plate to execute specially the thermal expansion, the internal stress can be easily controlled, and the thick soft magnetic film can be formed.

Title: Angular acceleration sensor
Inventor: WAKATSUKI GOROE
IPC: B60T8/171
Filed: 1987-09-25
Abstract: PURPOSE:To make it possible to actuate an output mechanism through a cam mechanism by occurrence of an angular acceleration of more than a certain value at a sample by connecting a flywheel installed at a drive shaft with a subject cam plate of the cam mechanism through a resilient drive member in such a way that the subject cam plate side can be freely displaced in the axial direction. CONSTITUTION:While a vehicle is running, a rotation torque of a pinion 23 is transmitted through a drive shaft 15, a clutch plate 75, a resilient drive member 76, etc., to a flywheel 72, which is rotated at a higher sheed than a rear wheel. If an angular deceleration occurs at the rear wheel by a braking operation in this condition, the flywheel 72 rotates for overrun together with a subject cam plate 83 relative to the drive shaft 15 by a rotary inertial force, and relative rotation occurs between both cam plates 82, 83. At this time, a locking tendency of rear wheels occurs by an excessive braking force, etc., and if the angular deceleration exceeds a certain value, the subject cam plate 83 displaces in the axial direction against a set spring 94 through a ball 84 so as to open a pressure discharge valve 20 through a lever 91 to reduce control oil pressure, thereby locking of rear wheels is avoided.
